The invention provides a nucleic acid, method and kit for a multi-liquid phase gene chip for simultaneously detecting and identifying components of three major categories of poultry, fish and ruminants. The nucleic acid comprises universal upstream primers, universal downstream primers, and universal probes for each of the above three categories of species. The method comprises the following steps: 1) extracting an animal genomic nucleic acid from a sample; 2) performing triple PCR amplification on the nucleic acid to obtain an amplification product; 3) performing xMAP triple microsphere suspension hybridization on the amplification product, and detecting a hybridization reaction signal; and 4) according the detection signal, determining a detection result of the sample to be tested. The method of the invention realizes simultaneous detection and identification of components of three major species of poultry, fish and ruminants, avoids separate detection and identification of single species one by one for the same purpose, and significantly reduces the detection cost and the detection time; and the method can efficiently prevent missed inspection and provide technical support for preventing false fraud in food and feed doping, and has important practical value.
